Hi
Add to the previous post, enabling IP routing doesn't need a DNS entry.
Telnet or connect to your fantastic 3400 switch by console cable and follow these steps:
1- Make sure you have all the 3 Vlans have IP addresses assigned:
Switch# sh ip ***
this will list all the IPs assigned per Vlan in the switch.
2- Enable IP routing from the config. prompt:
Switch#config
Switch(config)#IP routing
This is more than enough to enable routing on the switch.
3- Check the IP routing table,
Switch#show ip route *** this should show at least 3 IPs in the routing table, and if not
then make you have at lest one active link in each Vlan
Because, the Vlan IP won't be in the routing table until it has at lest one active link (untagged port connected to end device, or a trunk with tagged or untagged to another switch ....)
Also, make sure to update the firmware to latest.
Other vendors are charing MONEY for this facility, and i wonder why people who has HP doesn't enjoy it.
Maybe if HP decided to get money for that, every body will remember the free days :)
Good Luck !!!
